Rebecca Romijn has had a tough time escaping her ex-husband's name.
"Oh my God, it happened to me last night!" she said.
Romijn and O'Connell are parents to twin girls. She told the magazine that the pair handle parenting and household duties without outside help.
"We're each other's assistants. We pick up each other's slack. Whoever is less busy helps the busier one: 'Can you go pick this up for me?' or 'Can you book my flight?' That's what real life is," she said. "Once you start paying somebody else to do the grunt work, who are you?"
